Fizz Junior 🥤

Meet % — the remainder operator. It doesn't divide, it tells you what's left over after dividing.

print(7 % 3)      # ➜ 1   (7 = 3 + 3 + 1 left over)
print(9 % 3)      # ➜ 0   (nothing left over!)
print(10 % 5)     # ➜ 0

That zero is the useful bit. If the remainder is 0, it divides evenly — so this is how you test "is this a multiple of 3?":

if number % 3 == 0:
    print("multiple of 3!")

This is a famous job-interview puzzle. Real grown-up programmers get asked this. You're about to smash it. 💪

Your mission

Count from 1 to 20, printing one line per number — except when the number divides evenly by 3. Then print fizz instead.

So: 1, 2, fizz, 4, 5, fizz, 7, 8, fizz...
